Rake variance from factory

I've noticed that some V6s look like the rear is not as high as my GT. Also on another thread someone has Steeda Sport springs installed and their front/rear ground to wheel well measurement is 28"f / 28 1/4"r. My stock suspension is 28"f (more like 27 7/8" actually) and 29 1/4"r.

My question is will a lowering spring kit actually lower or does it get you to a certain point. In other words if my front is already just under 28", will I really get a 1.0 or 1.5 (depending on brand) drop or might it just stay close to where it is?

I am tempted to just put some rear springs on but I wouldn't mind getting rid of a little front dive on breaking/shifting.

What do you guys think?

I'm a believer in rake! a lot of people try to get rid of it on their Stangs With the www.GroundForce.com performance springs I put on my car they actually increased the rake a little!

If you are already around 28" I don't think you'll see much drop. I just put ultralites on and got about a 1/4" drop in front. Previously I had cut one coil from the rear springs to level out the car - and replacing those with the Steeda springs left it right where it was. My car is 28" on all four courners now. So, the car isn't much lower than it was, but with the new springs and d-spec shocks it's handles much better.

Is there some other factor beside the spring that determines the ride height on a stock vehicle?

What I am looking for is completely level like the Steeda Q's:

I'm not aware of anything. The front strut assembly is pretty simple - yet I've seen almost a 1" range of what "stock" height is. There are before and after pics of my car here: http://forums.bradbarnett.net/showpo...8&postcount=24

Nope, as far as I know the springs are basically the determining factor in ride hight, from the picture you posted I see some rake they are not completely level. I think the camera angle is deceiving you!

I don't see any rake, just look at the tire to wheelwell gaps on the Steeda's - they are nearly identical.

The GT-H has rake, the Steeda's do not. The line of the body has rake but I'm talking about the rocker area and wheelwell gap.

You are right, there does not seem to be any difference between your stock springs (w/rear cut) and the Ultralights. Do they ride much different than stock?

I wonder if the Sports would provide a slightly lower drop although Steeda's website says they are both the same drop.

The GT-H uses the FRPP handling pack.The rear end does not drop that much.I had this kit on my 06'GT(first pic after drop w/stock 17's).I dropped my 07'GT with Steeda.The drop was 1" up front,1 1/4" in the rear(second pic,18x9' all fours).Then I went to a 18x10 on the rear with 295/55/18 and the taller tire gave me back the rake but not the gaping hole between the tire and fender(third pic).Me happy,I like.The ride is not bad at all.

I've got Steeda sport springs on the front and rear. My son has just the rears on his '05 and I think it looks great.

I think it worked out well - I was reluctant to lower my car (other than to get rid of the rake) but finally took the plunge. I got the handling improvement without lowering much at all. Now I just wish I would have gotten them sooner.

Pat,
You didn't happen to measure from the ground to the center of the wheel well before and after did you?

Check out this post of FRPPs which is why I think there must be some variance from the factory which has much less gap on the rear than you did:

I see the what your speaking of...check this out.I also ran FRPP black 18" Bullitts and 20" Raceline GT's.Same lowering kit on the 06'GT.The larger the wheel the smaller the gap,go figure.The overall diameter of each set of tires was the same.(yeah,I'm a real wheel ****)

Sorry, but that is impossible. If the overall tire diameter is the same, the distance from the tire to the fender has to be the same.

I double checked.I made absolutely sure they were the same,maybe .1 inch off on the 20's.The only variable could have been that the springs settled from the first set to the third set of wheels.

I was going to ask if the rear springs settled. That's also why I was asking about measurements from ground to wheelwell.
